Skills

This plugin provides 5 skills that teach Claude about Mailprotector:

Skill	Description
`allow-block-rules`	Sender allow/block rules at all five scopes: downward inheritance (reseller rules apply to everything beneath), the listing that returns only directly-attached rules, create with `rule_type: allow\|block` and address-or-domain values, and the flat delete endpoint.
`customers-and-domains`	Customer lifecycle (create/edit/delete under the reseller), domain creation with the Pending → Active verification flow and verification_token, domain aliases, moving domains between customers, address discovery, and mail routing via email destinations and email sources.
`quarantine-and-messages`	Quarantine triage across all five scopes (reseller/customer/domain/ user_group/user): message fields (`quarantine_type`, `decision`, `score`, scoring `results`), releasing a single message via `/deliver`, bulk release via `/deliver_many` with its silent scope-mismatch skip and the `all_selected` release-everything switch, and the release permission flags in configuration.
`users-and-groups`	User groups as the service container (services get/update with its deactivate-what-you-omit semantics), user CRUD including create_many and find_by_address, user aliases, password resets, and user syncs — LDAP/AD source creation, Entra/Google console-only sources, sync schedules, and comparison-type filters.
`api-patterns`	Mailprotector MCP fundamentals: gateway header authentication (`X-Mailprotector-Api-Key` / `X-Mailprotector-Reseller-Id`) and its translation to the upstream Bearer token, the Provider → Reseller → Customer → Domain → User Group → User entity hierarchy, the router-pattern tool surface with `mailprotector_execute_tool` for the long tail, scope/scope_id consolidation, field-based list filtering, `page` pagination (max 50 on messages), and error handling.

Agents

This plugin provides 3 agents for autonomous task execution:

Agent	Description
`mailprotector-mailflow-auditor`	Use this agent when auditing Mailprotector mail flow, configuration, or allow/block posture across customers and reporting anomalies.
`mailprotector-onboarder`	Use this agent when onboarding a new customer onto Mailprotector end to end: creating the customer, creating and verifying domains, provisioning user groups and services, and populating users manually or via directory sync.
`mailprotector-quarantine-triager`	Use this agent when reviewing quarantined Mailprotector messages at any scope, hunting false positives, releasing held mail safely, or proposing allow rules for repeat offenders.
